This kit includes the fire control group, magazine catch assembly, bolt catch assembly, trigger guard, and all necessary springs, detents, and pins to make your stripped lower receiver functional. It's designed for builders who want reliable, mil-spec components without unnecessary extras.\u003c\/p\u003e\u003cp\u003eAll parts are manufactured to military specification tolerances with durable finishes. Installation requires basic armorer tools and familiarity with AR-15 assembly procedures. Builders should have a lower receiver vise block, roll pin punches, and patience when installing roll pins to avoid marring the receiver. This kit does not include a pistol grip or trigger guard roll pin—verify what your specific build requires before ordering.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Complete Lower Parts Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 \/ M4 Platform\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification:\u003c\/strong\u003e Mil-Spec Dimensions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Armorer-Level Assembly Required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Fire Control Group, Magazine Catch, Bolt Catch, Trigger Guard, Springs, Detents, Pins\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes Not Include:\u003c\/strong\u003e Pistol Grip, Buffer Assembly, Stock\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LanTac USA LLC","offers":[{"title":"Default Title","offer_id":47943840006399,"sku":"LAN01-PKIT-LP","price":44.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5584803.jpg?v=1766603289","url":"https:\/\/doublestackstore.com\/products\/lantac-m-spec-lower-parts-kit-ar-15","provider":"Double Stack Store","version":"1.0","type":"link"}
